I didn't get a sore head lol, I quit drinking also, I can't drink and not smoke atm, it's kinda like, I drink VERY VERY fast, and when I smoke it sort or, helps slow it down, I know this might sound stupid, but it worked for me...
And yeah cigs can save you from alot of awkward moments, true, but, at the same time it creates new opportunities for meeting girls too, so many girls HATE smokers, like seriously some girls look at you, see the cig, and just forget you exist, last month I was telling this girl I quit smoking, a girl that knew I smoked before, and she seemed REALLY impressed when I was telling her about the changes in my life, I find it so easy to approach girls cuz I simply don't care what they think lol, what's the point in worrying what someone thinks about you, when you don't even know them lol.
